JOHN P. GASZNER, OF FORT WAYNE, INDIANA, ASSIGNOR OF ONE-HALF TO FREDERICK MIGHAELS, OF SAME PLACE.

SPRING CURTAIN-ROLLER.

SPECIFICATION forming part of Letters Patent No. 341,648, dated May 11, 1886.

Application filed December 3, 1895. Serial No. 184,620. (No model.)

To all whom, it may concern: 1

Be it known that I. JOHN I. GASZNER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of 5 Indiana, have invented a new and useful Improvement in Spring Curtain-Rollers, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in spring curtain-rollers; and the novelty consists in the peculiar construction, combination, and adaptation of the various parts for service, substantially as hereinafter fully set forth, and specifically pointed out in the 1 claims.

The primary object of my invention is to provide a spring-roller with means whereby it can be used either as a stop-roller or a balance-roller, to provide means which shall be automatic and thoroughly effective in operation, and which shall be simple and durable in construction, not liable to get out of order, and cheap of manufacture.

In the accompanying drawings, Figure 1 is an elevation of my improved roller in proper position on the suspending hooks or brackets. Fig. 2 is a central vertical longitudinal sectional View through the spring-roller; Fig. 3 is a detached detail view of one of the cap pieces. Fig. 4 is a similar view of the other cap-piece of the roller. Fig. 5 is a view in detail of the cap shown in Fig. L, showing the device when used for a balance-roll; and Fig. 6 is a detail view of the lower bar of the ourtain-shade. Fig. 7 is a transverse sectional view on the line was of Fig. 1, showing the manner of supporting the roller.

Referring to the drawings, in which like letters of reference in the several figures de- 0 note corresponding parts, A designates the roller-supporting books or brackets,which are of any ornamental or preferred form and have threaded shanks for easily and quickly securing them in the window-frame in the 5 ordinary well-known manner.

B represents the roller proper,supported in the brackets; O,the shade secured to the-roller, and D the lower rail or bar of the shade. The lower end of the shade has a loop, 0,

formed therein, in which the rail D is removably secured, said rail being recessed longitudinally, as at d, and having a detachable weight-bar or plate, D, seated therein.

The roller B comprises a rotating shell or casing, E, tubular in form and having one end left open and the other end closed by a bearing'block, I), having a hollowed-out portion or seat, I), a non-rotating spindle or shaft,

F, seated at one end in the bearingblock b and projecting at one end beyond the same, a spring, G, coiled around the spindle or shaft F and secured at one end thereto and at its opposite end to the rotating tubular shell, and detachable cap-pieces H K, which are seated or secured in the supporting hooks 63 or brackets. A plate, h, is rigidly secured to the vertical face of one end of the roller shell or casing, and has an opening through which one end of the spindle is passed, and it is further provided with projecting {pins It, this plate forming part of the roller and providing a bearing for the spindle or shaft F. The cap H is chambered out, as at z, and has a socket, t", for the reception of the extreme outer end of the spindle, which is secured therein by a pin or bolt, The chamber 1 of the cap has a pawl, I, pivoted therein near its center, adjacent to the socket, and when the roller proper is removed from the brackx ets A, this pawl flies out by centrifugal force and catches one of the st0p-pins h, to prevent the coiled spring from becoming unwound and. losing its tension.

The end of the roller to which the cap K is applied has a plate, It, secured thereon, and this plate has a notched flange or pawl, j, at its middle and an outwardly-projecting stud, L, which is seated in a socket, m, of the cap K, and is free to turn or rotate therein when the tubular shell or casing E revolves. The outer end of the stud L is grooved at Z, and in this groove fits a pin or lug, Z, which serves to prevent longitudinal movement or displacement of the tubular shell in its rotatory movements, while at the same time it permits of said rotating movement. The cap K is chambered out at a, and near the periphery of the chamber is pivoted a gravitating-pawl, N, which is arranged over and adapted to engage one of the notches of the flangeor pawl j, to prevent rotation of the roller shell or casing E.

\Vhen the device is to be used as a balance I place by frictional contact between the opposshade-roller, a ring or band, 0, is placed over the notched flange j of the plate and the pawl reversed so that its tooth shall enter a notch, 0, in the walls of the chamber at of the cap K, (see Fig. 5,) the removable weight-bar or plate D being fitted in the recessed seat of the shade-rail D.

If the device is to be used as a stop-roller, the weightin theshade is removed and the ring or band 0 removed from the notched ledge or flangej,the pawl N entering one of the notches therein. h n the shade is drawn down,the tubular shell or casing E revolves on its stud L and the projecting end of the spindle to unwind the shade, and upon releasing the shade the pawl ll falls by gravity into one of the notches ot'the ledge or liangej. The gravity pawl permits of the downward movement of the shade without hinderance, and when it is desired to roll or wind the shade on the roller or the tubular shell it is moved very rapidly upward to the desired elevation,when the shade is held stationary to allow the pawl to drop into one of the notches ot' the ledge j to hold the shade at that elevation.

If the device is used as a balance shaderoller, the pawl N is thrown out of position, the ring or band 0 applied to the notched flange or ledge, and the weight D fitted in the seat in the shade-rail D, the weight being sufficient to equalize the retractile force of the spring and normally hold the shade stationary. \Vhen it is desired to adjust theshade vertically, the weighted lower end is grasped and either pulled down or lifted up. \Vhen it is pulled down, the spring yields, and when it is elevated the ret-ractile force of the spring rotates the tubular shell or casing, and thus winds up the shade. The cappieces are clamped in the brackets and prevented from rotating thereby, and the shade-rail is readily removable from its socket, for the purpose described.

In the sectional view shown in Fig. 7 of the drawings I have illustrated one form of bracket or hook, A, for supporting the roller in place. This bracket has a yielding clampingarm, (6, that binds upon the cappieces ot' the roller, and holds the cap-pieces immovably in l l l l t t t I t ing faces, and the bracket is further provided with a threaded shank that is adapted to be screwed into the window-frame or other place.

The device is simple, strong, and durable, thoroughly effective and automatic, can be quickly and readily converted from a stop to a balance roller, and vice versa, and is cheap.

Having thus fully described my invention, what I claim as new is 1. The combination of a rotating shell or casing, 21 spindle seated at one end therein, a rigid cap, H, having the free end of the spin dle secured therein, a shade, a rigid cap, K, having a reversible gravity-pawl, a plate, k, having a stud, Z, and a notched flange secured to the shell, a removable band, 0, and a detachable shadeweight, whereby the device is adapted for use as a stop-roller or a balance shaderoller, substantially as described.

2. The combination of a rotating shell or casing, a non-rotatable spindle, a spring, a rigid cap, H, having one end of the spindle secured therein, a shade attached to the shell, a rigid cap, K, having a reversible gravitypawl, a stud secured to the roller and journaled in the cap K, and provided with a notched ledge, a removable band or ring adapted to litover the ledge, and a removable shade-rail having a detachable weight seated therein, substantially as described.

3. The combination of a rotating shell or easing, a non-rotating spindle inclosed within and supported at one end in the shell or casing, the lived cappieces H K, the clampingbrackcts in which the cappieces are rigidly and detachahly supported, a notched bearing stud rigidly secured at one end to the shell or casing and journaled at one end to the cappiece K, and a pivoted gravity-pawl inclosed within a chamber of the cap K and adapted to engage the notch of the stud, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN P. GASZNER.
